Precalculus Demystified: A Self-Teaching Guide Book

It's a math book, so what can I say, other than there seemed to be enough examples on the subjects that I was interested in. The book covers a very wide swath of mathematics and so it isn't able to carry all of the topics far enough long for the reader to understand their ultimate usefulness. That being said, I had tried starting first with Calculus Demystified (the second book in this series) and ran into some stumbling blocks because of my weak background. I'll know better in a month, of how good this book was, when I see how well the road is paved ahead.
